Appiicationled January 23, 1908. Serial No. 412,302.

To all whom.y it may concern.'

Be it known that we, ELLswoRTnv N. SMITH and CHARLIE' WALKER, citizens of the United States, residing at Dewitt, in the county of Clinton and Stateof Iowa, have invented new and useful Improvements in Shock-Loading Machines, of which the following is a specification.

This invention relates to a shock loading device whereby shocks of fodder can be conveniently supplied to a shredding machine, or whereby shocks can be loaded on a wagon o1' transferred from one point to another in a simple and convenientl manner".

The invention has for one .of its objects to improve and simplify the constructiongand operation of machines of this character' so as.

to becomparatively easy and incx ensive to manufacture, readily manipulate and effective in operation.

A further objcetpi the invention is thev .y provision Yol a horscrdrawn shock loading machine having a suitable lifting mechanism which may be operated by hand, as in removing shocks iroin one point to another While the vehicle is stationary, or which canv be operated by the movement of the vehicle as in loading shocks u )on a moving wagon traveling alongside of tlie machine.

A further object of the invention is the provision of n. machine oi' this character including a removable. standard pivotally mounted and carrying a. boom, the standard and boom forming guides i'orthc flexible clement or cable to which the fork or other shock lifting device is attached, there being a suitable mechanism for turning the standard in" order t'o carry the shock to the desired peint of deposit. i

With these objects in View and others, as w,ill appear as the description proceeds, the ii vention comprises the various novel features of construction`v` and arrangement of parts which will be" more fully described ireinafter and s et forth. with particularity in the claims appended hereto.

In the accom anying drawings, which illustrate 'one oft e embodiments of the invention, Figure 1 is a perspective view of the machine.v Fig. 2 is a verticals'ection through vthe standard and boom with' portions broken away. Figy $is a rear. LView ofv the cable winding drum and ad'acent n arts for throwing the drum into an out o operation, portionsor` lthe parts being-shown in section. Fig.4fis a transverse section 'on line 4 --4,

Fig. 3. Fig.` 5 is a transverse section on line 5 5, Fig. 2, drawn on a reducedscale.

Similar reference" characters are employed to designate corresponding parts throughout the several views.

Referring to the drawings, A designates the body of the vehicle which may be of any suitable construction and consists in the present instance, of ay rectangular frame composed of side bars 1and end bars 2 and 3.

isposed under the front bar 3 isan axle 4" connected With the said bar by the pivot 5, there being front wheels 6 on the ends of the axle and a tongue 7, it being understood that the machine is intended to be drawn by horses. On the side bars. 1 at a point adjacent their rear ends are bearings 8 in which rotates an axle 9 to which the rear traction wheels 10 are rigidly secured..

Supported on the side bars 1 is a cross beamll that has an opening 12, as shown in Fig. 2, for receivin f the lower end of a tubular/Standard 13 which is provided with a collar 14 resting on bearing balls 15 so as to freely turn. On the u per end of the standard is secured, in fixed) position, an inclined boom 16 which is also tubular and open at both ends. On the ends of the boom are grooved pulleys or sheaves-17 and 18, over which passes the`cable or rope 19 which carries the usual fork or load-receiving device (not shown). At a )oint intermediate the ends of the standard 13 is an opening 20 through/which the cord 19 passes from/'the pnlley 17, ihe rope continuing downwardly through the Istandard and rearwardly from under the cross`beam 11. Secured to the standard -13 at the recess 20 is a .bracket 21 that supports the sheave or pulley 22, and supported on the under side of the beam l l is a bracket 23 on which is mounted the sheave 24,0ver whichthe cable 19 runs. By arranging the lifting element or cable in this manner, thestandard 13 can be readily turned without interference. from the cable. 'lhe standard 1s steadled by means of braces '.25

Y that have their lower ends secured to the side' bars 1 adjacent the. extremities thereof and their upper ends secured to a. disk or collar 26 that is arranged on the standard at a point immediately below the )ulley 22. These braces may be removabiy secured to' the bodv of the vehicle as b v means of bolts 27, so that they can be taken down when the machine is 1o be stored away, and in order to permit the standard to be removed, the disk 26 .ing the rod 34, there being a lug 35 on the under side of the keeper for engaging the member 31 to4 prevent the keeper from mov-- ing outwardly. By removing the keeper and lifting the standard a distance sufficient -to remove its lower end from the socket 12 in' the cross beam 11, the standard can be removed laterally from the machine. The disk 26 is also supported by vertical rods 34 disposed around the standard and having their lower ends secured to the cross beam 1 1.

The lifting cable 19 is operated by means of a drum 36 mounted on the rear vaxle 9 of the vehicle. Secured to the said axle by means of a set screw 37 is a clutch element 38 that has laterally-projecting fingers 39 adapted to engage in apertures or depressions 40 in the adjacent end face of the drum, so that by longitudinal movement of the drum, the latter can be clutched or unclutched with respect to the vrear axle. The drum is moved longitudinally by means of an operating lever 41, Fig. 1, that is pivoted at 42 on abracket,

43, and connected with the lever is a shifting rod 44 lthat carries atits 'inner end a forked. member 45 which engages in the peri heral' groove 46 of the sleeve 47 which is rigi ly secured to the end of the drum opposite from the clutch. The lever 41 has a latch 48 that engages notches 49 in the bracket 43 so as to hold the drum either in clutched or unclutched position. When the `drum is clutched to the rear axle, the movement of the vehicle will cause the drum to Wind the-lifting cable 19, and when the shock is raised to a suitable height, the vehicle is stopped and the standard 13 turned to bring the shock to the proper point of deposit, and thereupon, the operator unclutches the drum by throwing the lever 41 outwardly for the purpose of permitting the drum to unwind under the weight of Jthe shock to deposit the latter.

For conveniently turning the standard, the stem is provided with sprocketwheel 51 at a suitable point around which passes a sprocket chain .32 that is actuated by a small sprocket wheel 53 mounted on the outer end of the beam 1 l and arranged on a crank shaft '54 so thai the operator. while standing at one side of the vehicle, can manipulate the crank to swing the boom 16 back and forth. The ends'ofthe boom are pla-ced on' the standard by means of braces 55 thathave their lower ends secured to the standard andtheir upper ends secured to the nps .36 and clamped to the extremities of the boom.

It may be desirable for some work to oper ate the drum 36 by hand, and for this purpose,

.l l i i vwheel 61 for turning the drum, there being a crank 62 on the ends of the said shaft for turning the same. sprocket wheel 61 is mounted to rotate freely on the sleeve 47 and carries a spring-pressed pawl l63 which cooperates with a ratchet -wheel 64 to turn the drum. The sprocket,

wheel 61 is held between a shoulder 65 on thf.- sleeve 47 and the ratchet wheel 64 and moves with the drum 36 when the latter is shifted longitudinally for clutching and unclutching it to and from the rear axle. The teeth 66 of the ratchet wheel 64 are so shaped that the)` will ride under the pawl so'that the drum 36 can freely rotate with the rear axle when a shock is lifted through the movement of the vehicle, and furthermore, when the drum is rotating with the Arear axle, the sprocket wheel is idle and stationary. When the crank shaft 57 is turned for lifting a shock by hand, the pawl 63 will engage the ratchet Wheel 64 and thus turn the drum for winding the cable 19 and Iwhen the shock is to be lowered, the operator'releases the crank 62 so that the'weight of the shock will cause the `and a band 7 0 ,arranged to frictionally grip As shown in Fig. 3, the

the drum, the band being actuated by thef lever 71.

F rom the foregoingdescription, taken in connection with the accompanying drawings, the advantages of the construction and of the method of o )eration will be readilyl aparent to those s illed in the art to which the invention appertains, andwhile We have described the principle of operation of the invention, together with the appara-tus which `we now consider to be the best embodiment thereof, we desire to have it understood that the apparatus shown 1s merely illustratn'e.w
